Previous studies have documented that exposure to elevated Carbon dioxide (CO2) causes impaired antipredator behavior by coral reef fish in response to chemical cues associated with predation. However, whether ocean acidification will impair visual recognition…

Plastic debris litters aquatic habitats globally, the majority of which is microscopic (< 1 mm), and is ingested by a large range of species. Chelsea M. Rochman et al, University of California, US, show that fish, exposed to a mixture of polyethylene with c…

Marine food webs are the most important link between the global contaminant, methylmercury (MeHg), and humanexposure through consumption of seafood. Jennifer A. Dijkstra et al, Wells National Estuarine Research Reserve, US, look at how warming temperatures may…

Temperature is one of key environmental parameters that affect the whole life of fishes and an increasing number of studies have been directed towards understanding the mechanisms of cold acclimation in fish.

There is an increasing need to evaluate the links between the social and ecological dimensions of human vulnerability to climate change. Joshua E. Cinner et al, James Cook University, Australia, use an empirical case study of 12 coastal communities and associa…

As atmospheric CO2 levels rise, the CO2 concentration in ocean surface waters increases through a process commonly referred to as ocean acidification. Recently, surprising behavioural modifications have been detected in the early life stages of tropical coral …
